3 * Version 3.2.9 released.
5 * Added extension function <> which is
6 mapped to the ST_Centroid(geometry) extension function of PostGIS.
7 See also: <>.
9 * Added extension function <> which is
10 mapped to the ST_MakeLine(geometry, geometry) extension function of
11 PostGIS. See also: <>.
13 * Added PostGIS vocabulary class.
15 * Added support of all SPARQL result types provided by Sesame (json,
16 xml, csv, tsv, binary). To get the respective writer, just prepend the
17 string "SPARQL/", e.g., "SPARQL/JSON". This is to ensure that we
18 support all SPARQL result formats of the SPARQL Protocol.
20 * Fixed a bug where a non-implemented extension function would make
21 Strabon throw a NULL pointer exception. Now we get away with it
22 through a warning.
24 * Strabon endpoint now publishes the URIs of the supported units of
25 measure for use in strdf:distance and geof:distance functions of
26 stSPARQL and GeoSPARQL, respectively. The URIs are those defined by
27 OGC Units of Measure 1.0 specification which may be found at
28 Strabon endpoint publishes
29 the URIs at http://localhost:8080/endpoint/Capabilities.
31 * Created new module with name 'vocab` and artifactId
32 'strabon-vocabulary` and moved there. Other
33 vocabularies have been added as well, such as Simple Features, and
36 * Strabon endpoint now publishes the URIs of the supported extension
37 functions for stSPARQL and GeoSPARQL. One should access them by
38 hitting the link http://localhost:8080/endpoint/Capabilities.
40 * Support for parsing EPSG URIs in geometry literals with datatype
41 geo:wktLiteral.

44 Tue Mar 26 13:28:26 2013 Pyravlos Team
46 * Version 3.2.8 released.
48 * Added support for handling (storing/querying) GeoSPARQL datatypes.
49 (bug #31:
51 * Fixed a bug in StoreOp that wouldn't close the connection, neither
52 rollback the transaction upon an exception. This had as a side effect
53 the abnormal termination of StoreOp (through for example the use of
54 Ctrl-C signal) which was leaving the database locked.
56 * Fixed bug where spatial aggregates (e.g., union) didn't work as
57 expected when the query didn't contain a `GROUP BY' clause.
58 (bug #22:
60 * Updated GeoSPARQL namespaces and fixed function names to comply with
61 the GeoSPARQL specification.
62 (bug #25:
64 Wed Jan 09 18:06:41 2013 Pyravlos Team
66 * Version 3.2.7 released.
68 * Add an extension function
69 <> for computing the
70 span (in milliseconds) between two timestamps.
72 * Added an <endpoint-exec> module. This module builds an executable jar file
73 with an embedded Apache Tomcat 7. To create and run the executable jar just
74 type:
75 $ mvn clean package
76 $ java -jar endpoint-exec/target/strabon-endpoint-executable-*.jar
78 * Modified strabon script and postgis/monetdb.StoreOP class to get an
79 option for storing a RDF file in a named graph. Moreover, the RDF
80 format of the input RDF file now is given as an option (still, if it
81 is missing, it is assumed that the input is in N-TRIPLES format). The
82 option for the format is -f and the option for the named graph is -g
83 (takes a URI as an argument).
85 * Modified the names of the stSPARQL extension functions that
86 utilize the minimum bounding boxes of the involved geometries.
88 Tue Dec 11 19:33:45 2012 Pyravlos Team
90 * Version 3.2.6 released.
92 * Modified the names of the stSPARQL extension functions to comply
93 with the OGC Simple Features Access standard.
95 Tue Dec 11 00:11:43 2012 Pyravlos Team
97 * Version 3.2.5 released.
99 * Added support for querying temporal information. This functionality
100 may be found in the `temporals' branch.
102 The datatypes <> and
103 <> are used to
104 represent periods and instants respectively.
106 The valid time time of triples is represented using quadtruples,
107 with the valid time annotation(instant or period) being the
108 fourth element of the quad. In the same way, temporal triple
109 patterns are used in queries to retrieve the valid time of
110 triples.
112 Some functions have been renamed (their URIs have changed) to
113 follow the names of the respective relations of Allen's
114 interval algebra and other functions have been added.
116 The following temporal functions are supported:
117 during, periodOverlaps, equalsPeriod, nequalsPeriod, adjacent,
118 before, after, overleft, overright, meets, starts, finishes,
119 period_intersect, period_union, preceding_period, and
120 succeeding_period.
122 * Changed behaviour of Strabon and Strabon Endpoint for connecting to
123 a spatially-enabled database. Only one instance of Strabon is allowed
124 at a time.
126 * Implemented a Java client for Strabon Endpoint. The client should be
127 used only with endpoint versions >=3.2.5. The implementation may be
128 found int the `endpoint-client' submodule of maven. Currently, only
129 querying of Strabon Endpoints is supported.
131 * Added support for requesting the capabilities of Strabon Endpoint
132 (fixes Bug #20 <>). See
133 changesets f840796400bf and ?<TBC>? for specific details and how you
134 can determine the capabilities of older endpoints (versions <= 3.2.4).
136 * Updated KML writer to include the projected variables of an stSPARQL
137 query in "ExtendedData" and "Data" tags. This is the proper way to
138 do it if we need to convert a KML to a ESRI shapefile and also include
139 such information as attributes for a feature. See related pages from
140 KML specification:
141 <>
142 <>
144 * Added user authentication for storing RDF data through Strabon
145 Endpoint. The credentials are specified in
146 WEB-INF/ file.
148 * Strabon Endpoints now limits the number of the results to a maximum
149 one. The maximum number is specified in the beans.xml file. This
150 corresponds to parameter "maxLimit". The endpoint script has also been
151 updated correspondingly; the limit can be given using the option "-l".
152 One can disable limiting of query results, by setting the "maxLimit"
153 parameter to 0. Addresses Bug #6
154 (<>).
156 * Added "Known Issues" section to README.
158 * Added -m (more memory) and -M (much more memory) options in strabon
159 script for out-of-memory exceptions.
161 * Fixed Bug #10 (<>). Now
162 KMLWriter handles more geometric types (other than polygons). See
163 changeset 9a3bfee64a39.
165 * Menu and navigation in Strabon Endpoint has changed to use jquery.
166 The menu is now populated using the queries placed inside the beans.xml.
168 * Added BrowseBean and browse.jsp for browsing the RDF data using the
169 Strabon Endpoint.
